Description

Technical Field

[0001] This utility model relates to the field of wiring harness equipment technology, and more specifically, it relates to a wiring harness structure for electrical renovation. Background Technology

[0002] In electrical renovation, the core solution to the problem of mixed and disordered wiring is to standardize and straighten the wiring. The key to organizing and tidying up messy wiring is to use wiring harnesses and other wiring harnesses to help arrange the wiring, so that the originally tangled and intertwined wiring becomes orderly, which not only eliminates the risk of short circuits and leakage, but also provides convenience for subsequent maintenance.

[0003] In existing technologies, cable management boards mostly adopt a fixed, integrated design with a fixed number of cable hole diameters that cannot be adjusted. This presents significant limitations when adapting to different numbers of cable harnesses. When the number of cable harnesses to be fixed is small, choosing a board with fewer hole diameters may meet the current needs, but when the number of cables increases, it is necessary to disassemble and replace the cable management board with a new one. If a board with more hole diameters is chosen to avoid future replacements, a large number of hole diameters will be left unused, occupying usable space in the electrical cabinet, resulting in low utilization of the cable management board and additional material waste.

[0004] Therefore, in order to solve the above problems, we propose a cable bundle structure for electrical renovation. Utility Model Content

[0005] To address the problems mentioned in the background section, this utility model provides the following technical solution:

[0006] An electrical wiring harness structure includes a mounting frame and multiple sets of wiring harness assemblies connected to the mounting frame. Each set of wiring harness assemblies can be displaced along the surface of the mounting frame to adjust its relative position to the mounting frame. Each wiring harness assembly consists of a fastener that engages and limits one side of the mounting frame and a wiring member that is slidably connected to the other side of the mounting frame. Multiple sets of limiting holes are distributed on the surface of the mounting frame along the displacement direction of the wiring harness assembly. The fastener is provided with an engaging connector that matches the limiting hole and a lifting assembly that can drive the engaging connector to move and extend.

[0007] Furthermore, the fastener includes a first housing, the lifting assembly is a lifting block movably disposed within the first housing, the setting direction of the engaging connector is perpendicular to the setting direction of the lifting block, and when the lifting block moves horizontally within the first housing, it can drive the engaging connector to extend vertically out of the first housing.

[0008] Furthermore, the lifting block has an inclined sidewall at a preset angle to the horizontal plane, and the bottom end of the engaging connector abuts against the inclined sidewall.

[0009] Furthermore, a first limiting rod is provided inside the first housing along the extending direction of the lifting block, the lifting block is slidably disposed on the first limiting rod, and a first elastic element is provided between one end of the lifting block and the side wall of the first housing on one side.

[0010] Furthermore, a second elastic element is provided between the engaging connector and the top wall of the first housing.

[0011] Furthermore, a fixing member is provided between the lifting block and the first housing. The fixing member includes a first limiting block fixed to the lifting block and a movable lever block that can stop and limit the first limiting block. The movable lever block can switch the limiting relationship with the lifting block by changing its relative position with the first limiting block.

[0012] Furthermore, a second limiting rod is provided between the first housing sidewall and the movable lever, the movable lever is slidably disposed on the second limiting rod, and a third elastic member is provided between the movable lever and the first housing sidewall on one side, the two ends of the third elastic member being fixedly connected to the first housing sidewall and the movable lever, respectively.

[0013] Furthermore, the movable lever and the lifting block are respectively connected to a first control key and a second control key.

[0014] Furthermore, the wire harness includes a second housing connected to one side of the first housing. The surface of the second housing has multiple sets of through holes for the wire harness to pass through. Two movable clamping plates that can be displaced radially along the through holes are symmetrically distributed in the through holes.

[0015] Furthermore, multiple sets of third limiting rods are fixed between the two side walls of the second housing. The third limiting rods are distributed on both sides of each set of through holes. The two sides of the movable clamping plate are slidably connected to the third limiting rods respectively. A fourth elastic element is provided between the movable clamping plate and the side wall of the second housing closest to one side.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This utility model features a separate installation design for the mounting bracket and the wire harness assembly. It can accurately match the corresponding number of wire harness assemblies according to the actual number of wire harnesses, avoiding excessive holes that occupy the usable space in the electrical cabinet. When adding or removing wires later, the corresponding number of wire harness assemblies can be added or removed directly without replacing the entire board, saving on usage and maintenance costs. The flexible wire harness assembly can conform as closely as possible to the actual route of the wires, without forcibly pulling the wires to change their path. This reduces wire damage and allows for a neat and orderly arrangement of the wires, facilitating subsequent inspection and positioning. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Please see Figure 1-9 An electrical modification wiring harness structure includes a mounting frame 1 and multiple wiring harness assemblies connected to the mounting frame 1. The mounting frame 1 is a rectangular box with a hollow interior. One side wall is a closed surface, which serves as the mounting surface for the equipment. The equipment is connected to other equipment via connecting lugs fixed to the mounting surface. The other three sides of the box are open, allowing the wiring harness assemblies to enter from one side and slide between the upper and lower sides of the box. Rectangular notches for wires to pass through are provided on the top and bottom walls of the box. The wiring harness assemblies are also rectangular to facilitate better side-by-side arrangement and save space. To ensure stability during movement, limiting protrusions extending in the direction of travel are provided on the upper and lower sides. The mounting frame 1 has sliding grooves that match these protrusions.

[0033] Each group of wire harness assemblies can be displaced along the surface of the mounting frame 1 to adjust their relative position to the mounting frame 1. By changing the position of the wire harness assemblies on the mounting frame 1, the wiring requirements of different incoming lines can be better adapted. This allows the wire harness assemblies to be flexibly adjusted according to the actual route of the line, so that the original route of the line does not need to be excessively changed to accommodate the wire harness holes, thus protecting the wire body and keeping the overall wiring neat and tidy along the actual path.

[0034] The cable harness assembly consists of a fastener 2 that engages and limits one side of the mounting frame 1 and a cable harness 3 that slides and connects to the other side of the mounting frame 1. Multiple sets of limiting holes 4 are distributed on the surface of the mounting frame 1 along the displacement direction of the cable harness assembly. The extension direction of the limiting holes 4 is perpendicular to the setting direction of the cable harness assembly. The fastener 2 is provided with a engaging connector 202 that matches the limiting holes 4 and a lifting component that can drive the engaging connector 202 to move and extend.

[0035] The fastener 2 includes a first housing 201 and a lifting component, which is a lifting block 203 movably disposed within the first housing 201. The first housing 201 is a hollow rectangular box. The setting direction of the engaging connector 202 is perpendicular to the setting direction of the lifting block 203. When the lifting block 203 moves horizontally within the first housing 201, it can drive the engaging connector 202 to extend vertically out of the first housing 201. The extended engaging connector 202 can be inserted into the limiting hole 4 on the mounting bracket 1. The engaging connector 202 and the limiting hole 4 are locked together, so that the fastener 2 and the mounting bracket 1 are engaged.

[0036] One end of the lifting block 203 has an inclined sidewall at a preset angle to the horizontal plane. To ensure the stable connection between the fastener 2 and the mounting bracket 1, two sets of locking connectors 202 are provided, and they are symmetrically distributed up and down with the center line of the lifting block 203 as the axis of symmetry. The inclined sidewalls of the lifting block 203 are also provided in two sets to meet the lifting requirements of the locking connectors 202, and they are also symmetrically distributed. The bottom ends of the locking connectors 202 respectively abut against the inclined sidewalls. When the lifting block 203 moves toward the locking connectors 202, its inclined sidewalls move along with the main body of the lifting block 203 and begin to squeeze the locking connectors 202 on both sides to extend outward from the first housing 201.

[0037] A first limiting rod 207 is provided inside the first housing 201 along the extending direction of the lifting block 203. There are two sets of the first limiting rod 207. The two ends of the first limiting rod 207 are fixedly connected to the two side walls of the first housing 201 respectively. The lifting block 203 is provided with a through hole adapted to the first limiting rod 207. The first limiting rod 207 passes through the through hole, so that the lifting block 203 can slide along the outer wall of the first limiting rod 207. When the lifting block 203 lifts the engaging connector 202, a first elastic element 208 is provided between one end of its forward direction and the side wall of the first housing 201 on one side. The first elastic element 208 is preferably a spring. The spring is sleeved on the outer wall of the first limiting rod 207, and the two ends of the spring are fixedly connected to the side wall of the first housing 201 and the lifting block 203 respectively.

[0038] The engaging connector 202 consists of a main rod and auxiliary rods distributed on both sides of the main rod. A connecting crossbar is fixed between the bottom of the main rod and the auxiliary rods. The fork-shaped design makes the connection between it and the mounting bracket 1 more stable. A second elastic element 210 is provided between the main rod and the top wall of the first housing 201. The second elastic element 210 is preferably a spring. The spring is sleeved on the outer wall of the main rod, and the two ends of the spring abut against the top wall of the first housing 201 and the connecting crossbar at the bottom of the main rod, respectively.

[0039] A fixing component is also provided between the lifting block 203 and the first housing 201. The fixing component includes a first limiting block 211 fixed on the lifting block 203 and a movable lever 206 that can stop and limit the first limiting block 211. By using the movable lever 206 to limit the first limiting block 211, the lifting block 203 is fixed on the first limiting rod 207 after lifting the engaging connector 202, thereby fixing the position of the engaging connector 202 and ensuring a stable connection between the first housing 201 and the mounting bracket 1.

[0040] A second limiting rod 212 is provided between the side wall of the first housing 201 and the movable block 206. The second limiting rod 212 is symmetrically distributed on both sides of the movable block 206. One end of the second limiting rod 212 is fixedly connected to the side wall of the first housing 201. The movable block 206 is slidably disposed on the second limiting rod 212. A third elastic element 209 is provided between the movable block 206 and the side wall of the first housing 201 on one side. The third elastic element 209 is preferably a spring. The spring is sleeved on the outer wall of the second limiting rod 212. Both ends of the spring are fixedly connected to the movable block 206 and the side wall of the first housing 201, respectively.

[0041] The first limiting block 211 is a wedge-shaped block, and the movable lever 206 is a U-shaped plate. The top ends of the extension arms on both sides of the U-shaped plate have inclined walls that fit against the inclined sidewalls of the first limiting block 211. In the initial state, there is a gap between the first limiting block 211 and the movable lever 206, which is greater than the length of the first limiting block 211. As the lifting block 203 moves on the first limiting rod 207, the inclined sidewalls of the first limiting block 211 begin to contact and press against the inclined sidewalls of the movable lever 206. As the two forces press against each other, the movable block 206 gradually moves away from the first limiting block 211. During its displacement, the movable block 206 presses against the third elastic element 209 on the second limiting rod 212 until the first limiting block 211 completely passes the movable block 206. Under the elastic force of the pressed third elastic element 209, the movable block 206 begins to approach the first limiting block 211. At this point, the movable block 206 abuts against the vertical side wall of the first limiting block 211, thereby achieving the blocking and limiting of the lifting block 203 by the movable block 206.

[0042] If the movable lever 206 is pushed further until its vertical sidewall completely passes the vertical sidewall of the first limiting block 211, the movable lever 206 can no longer block the lifting block 203 due to its hollow design in the middle. At this time, the lifting block 203 will quickly reset under the elastic force of the first elastic element 208 located on the first limiting rod 207. During the reset process of the lifting block 203, the bottom end of the engaging connector 202 will also gradually descend along the inclined sidewall of the lifting block 203, and finally retract into the first housing 201 to achieve reset. The movable lever 206 switches its limiting relationship with the lifting block 203 by changing its relative position with the first limiting block 211.

[0043] The movable lever 206 and the lifting block 203 are respectively connected to the first control key 205 and the second control key 204. The first control key 205 and the second control key 204 are respectively located on the outside of the first housing 201. The first control key 205 and the second control key 204 are respectively fixedly connected to the movable lever 206 and the lifting block 203 through connecting rods. The two connecting rods are respectively slidably connected to the side wall of the first housing 201.

[0044] The cable harness 3 includes a second housing 302 connected to one side of the first housing 201. The second housing 302 is the same as the first housing 201, and is a hollow rectangular structure. The second housing 302 is fixedly connected to the side wall of the first housing 201 on the corresponding side. The surface of the second housing 302 has multiple sets of through holes for the cable harness to pass through. Two movable clamping plates 301 that can be radially displaced along the through holes are symmetrically distributed in the through holes. By adjusting and clamping the movable clamping plates 301, more cable harnesses can be accommodated.

[0045] Multiple sets of third limiting rods 303 are fixed between the two side walls of the second housing 302. Each set of third limiting rods 303 is symmetrically distributed on both sides of each through hole. The two sides of the movable clamping plate 301 are slidably connected to the third limiting rods 303. A fourth elastic element 304 is provided between the movable clamping plate 301 and the side wall of the second housing 302 closest to one side. The fourth elastic element 304 is preferably a spring. The spring is sleeved on the outer wall of the third limiting rod 303. The two ends of the fourth elastic element 304 abut against the side wall of the second housing 302 and the side wall of the movable clamping plate 301, respectively.

[0046] Working principle: First, select an area with a large number of messy wires and fix the mounting bracket 1. Then, assemble the wire harness assembly according to the actual number of wires. Insert the wire harness assembly from one side of the mounting bracket 1. Then, hold one end of the fastener 2 and move it to a suitable installation position. At this time, push the second control key 204. The second control key 204 pushes the lifting block 203 located inside the first housing 201 through the connecting rod on one side to push out the engaging connector 202. The engaging connector 202 extending out of the first housing 201 engages and limits with the limiting hole 4 on the mounting bracket 1. After fixing the wire harness assembly, let the wire harness pass through the through hole opened on the wire harness 3. The two movable clamps 301 in the through hole achieve a stable clamping of the wire harness.
